possible to remove task activity?

[jdoran]

I'm messing around with the quest journal, and am wondering if there is some way to remove a completed activity from the displayed list. (I'm sending packets to the client from my code, not using the existing task code)

The reason I'm messing with this is that I am curious if I could use the journal as a window onto a larger quest (displaying 19 activities out of a larger pool). I've spent 5 or 6 hours messing with the journal and am happy with the results, except for the case where the last few activities are completing (and the displayed list should shrink).

If I have two activities and complete the 2nd, this 2nd activity will still
remain. I can overwrite it with new data, but I cannot clear out that slot. The "done" and zone names at the right of the activity are spoiling the effect.

I've tried poking around with the OP_TaskActivity packet, thinking I could trick the client into thinking there was no longer an activity in that position. The client usually ignores my efforts.

Does anyone have any thoughts on this?
